P 061 – Determination of biomechanical influences of increased femoral anteversion (twisted leg) on running for developing individual

Abstract

Increased femoral anteversion (IFA) angle, the forwardly rotated femoral head is high in newborn, decreases by ages and reaches normal values by completion of bone growth [1,2]. Our previous study demonstrated that, for neurologically intact participants, IFA not only augments internal-hip-rotation and foot progression but also reduces the peak knee extension and total knee range in sagittal plane during walking [3]. During running, knee flexion range and the load on extension mechanism are higher than walking. Therefore, the relation between increased hip internal rotation and anterior knee pain (AKP) during running in older ages still under investigation.
